| Abstract: | This design is based on the theorem of fr e quency and period testing with high accuracy and constant error by using Lattice 's in-system programmablity device ispLSI in our hardware design. Every item of testing in our design demostrates that the theorem is reasonable. The further t heoretical analysis on the theorem is made in this paper.The hardware design is also given. |
